A blindfold is a piece of fabric or material used to cover the eyes, preventing the wearer from seeing. It is often used in games, such as pin the tail on the donkey, or in activities that require sensory deprivation, like trust exercises. Blindfolds can be made from various materials, including cotton, silk, or synthetic fabrics. In addition to recreational uses, blindfolds have practical applications in medical settings, such as during certain eye examinations or procedures. They can also be used in meditation practices to enhance focus by eliminating visual distractions.
